Resection Specimens

Femoral heads or large chunks of bone require adequate fixation and are then cut coronally with a junior hacksaw or vibrating table saw. The thin, sawn slices are placed in 10% formic acid for decalcification. The decalcified slices are then serially blocked, labelled and submitted in toto.

Amputation specimens are examined to:

• evaluate the resection margins including vessel involvement.

• determine the extent of bone involvement.

• evaluate the tumour necrosis, a measure of response to prior chemotherapy.
